COM PARTMENT-TANK.

SPECIFICATION forming part of Letters Patent No. 349,528, datedSeptember 21, 1886.

Application filed July 3, 1885. Serial No. 170,661.

To all whom it may concern:

Be it known that I, BENJAMIN O. SHAW, a resident of Racine, \Visconsin,have made certain new and useful Improvcmentsin Compartment-Tanks, adescription of which is set forth in the following specification,reference being made to the accompanying drawings, in the severalfigures of which like letters indicate like parts.

My invention consists of a portable tank divided into separatecompartments, provided with internal discharge-pipes leading separatelyfrom the several compartments to a measure-box attached to the rear endof the tank, which is mounted upon a suitable truck, inside of whichmeasure-box faucets are attached to each of the several discharge-pipes,and will be understood from the following description.

I11 the drawings, Figure 1 represents aside view of a three-compartmenttank and itssup-. porting-frame, the measurebox shown in dotted lines atthe rear, thc frame adapted to be mounted on any suitable truck fortransportation. The front head of the tank rises to one-ha1f the heightof the tank, then runs back horizontally with a convex curve tosufficient depth to make room for awagon-seat for the driver, then riseswith a concave curve perpendicular to the top of the tank, as shown, theportion adapted to receive the seat being marked 8. d, d, and d aredomes connected by suitable collars to the top of the tank,openinginside each compartment. These domes are closed by covers, with each ofwhich is connected a hand-screw, 71s, passing through a curved brace,1), into a suitable nut connected with the cover, and this curved braceis hinged by means of a bolt passing through collar 0 upon a projection,p rising in the rear of the dome and bolted to it, as shown in Fig. 3,the foot of this brace b curving under the front of the flanged top ofthe dome, as shown in Fig. 1. By means of this screw the cover may beraised from the opening of the dome and readily removed, the brace bacting as a sort of crane to swing the cover around on a pivot,completely uncovering the whole month, for the convenience of fillingeach com- 5o partment of the tank.

In Fig. 2 is shown a cross-section of the tank (No model.)

It, showing the form of the rear brace-plate bp, havingthree openings,through which the several dischargepipes pass. Fig. 3 is a front viewshowing the elevation of the seat and the front strap, st, which,passing over the seat-step and down through the sides of the frame, issecured on the under side thereof by means of nuts, and assists in-preventing the rolling of the tank in its cradle. Fig. 3 is a sectionalview of the pivot of the curved brace- Fig. 3" is aplan view of one ofthe domes on a reduced scale. Fig. 4tis a vertical section ofa portionof the tank, showing the front brace-plate secured at the bottom of thetank upon the forward side of the frontpartition. Fig. 5 is alongitudinal section of the entire tank, showing the back of the seat,the three compartments 1, 2, and 3, separated by the two centralpartitions, and the several braceplates bp in place, each one rivetedand so]- dered to the bottom of the tank and to the side of thepartition, against which it rests. These brace-plates are curved uponthe bottom, so as to fit the concave surface of the tank below, and areformed flat on the sides, so as r to rest against the fiat partitions.Threaded openings are formed in these brace-plates, as shown in Fig. 2,the front one having one opening, the central one two openings, and

the rear one three openings. The pipe 1), which passes from the forwardcompartment, is screwed into the opening in the brace-plate bp throughan opening in the front partition, passes through an opening into thenext brace- 8 5 plate, and through the second partition, and throughthercar brace-plate, and terminates in an elbow-joint connected with afaucet, as shown in Fig. 5. The pipe 19 is connected with thebrace-plate on the inside of the com- 0 partment 2, passes through thatand the brace-plate in the rear, and there terminates in an elbow-joint,with which the faucet is connected. This serves to discharge the oilfrom the compartment 2 as pipe 12 serves to g5 discharge the oil fromthe compartment 3, while from compartment 1 the short pipe 1) leadsdirectly through the rear brace-plate, terminating in a faucet betweenpipes 12 and p. On the inside of compartment 1 and against the partitionwhich separates conrv partrnents 1 and 2 threaded couplings are l Pscrewed upon the ends of pipes p and 19 to form amore perfect joint,preventing leakage. These couplings, after being screwed onto the pipesmentioned, may also be soldered, if desired, to make them more secureagainst any possible leakage of oil from one compartment the top resting011 and running across the tank under the seat, and to which the seat isattached, the ends of this strap running down through the woodenframe,with washer and screw-nuts drawing against the under side thereof.This fastens the forward end of the tank to the frame solidly, andprevents the tank from rocking in the cradle. From one or more of thedomes on top of the tank are brace-rods In, In", and Zn, hinged to acollar encircling the dome, running down on either side of the tankthrough the cross-sills of the frame, and secured on the under sidethereof by means of screw-nuts, as shown in Fig. 1. In the rear thestrap st, passing over the tank and down on either side, stirrupshaped,passes through the rear crosssill, and is secured on the under sidethereof by means of screw-nuts. These several brace-rods and straps holdthe tank firmly to the frame and tached to the truck-gearing by means ofriserblocks in the usual manner.

Iam aware that compartment-tanks mounted on truck-gearings are not new,and do not broadly claim the same as my invention.

Vhat I do claim as my invention, and desire to secure by Letters Patent,is the following:

1. The tank If, having its front head made in one piece of metal risingperpendicular to the height desired for the seat, thence passingbackward in a horizontal line a sufficient depth, thence by a turn to aperpendicular, and attached with rivets, substantially as described.

2. The tank 25, having two or more compartments with internal pipesleading therefrom and provided with inside brace-plates, bp, throughwhich the discharge-pipes pass, substantially as described.

3. A portable compartment-tank having its front portion cut away toreceive the seat for the driver, provided with domes to each compartmenthaving movable covers secured by hand-screws hs, adapted to be swungaround upon'acurved brace, I), substantially as described.

4:. In a portable compartment tank, its front portion cut away toreceive the seat of the driver, the compartments 1, 2, and 3, eachprovided with its separate dome and a separate internal dischargepipe,the latter passing through the brace-plates bp, bolted to the inside ofthe tank and against the wall of each compartment, the whole set in awooden cradle, as shown, and connected thereto by means of brace-rodsand straps, and mounted upon a suitable truck for transportation, allcombined substantially as described.

In witness whereof I have hereunto set my hand this 23d day of June,1885.

BENJAMIN O. SHAW.
